VENEER-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 609,513, dated August23, 1898.

Application filed August 9, 1897.

To all whom it may concern.

Be it known that I, GEORGE EZRA MORTON LEWIS, a British subject,residing at Truro, in the county of Colchester, in the Province of NovaScotia and Dominion of Canada, have invented certain new and usefulImprovements in Veneer-Cutting Machines, of which the following is aspecification.

My invention relates to improvements in veneer-cutting machines in whichthe bolt of wood from which the veneer is out is revolved in continuouscontact with a cutting-knife, whereby a connected thin spiral sheet issevered from the revolving wood; and the objects of my invention are,first,to' provide means whereby curved Veneers may be out, and, second,to provide means by which a curved or straight veneer can be cut andchamfered on either one or both edges to a desired bevel by thesimultaneous use of different knives. I attain these objects by themechanism illustrated in the accompanying drawings, in which" Figure 1is a face elevation of an ordinary veneer-cutting knife-block embodyingmy invention. Fig. 2 is a vertical section of the same on line a I),looking in the direction of the arrow and showing a portion of arevolving veneer-bolt in a position for cutting into veneers. Fig. 3 isa partial section on line 0 cl of Fig. 2, looking toward the face of theknife-block and having the chamferingknives removed. Fig. 4 is adisconnected plan of a curved presser-bar,a curved cuttingknife, and thechamfering-knives in place. Figs. 5 and 6 are edge views of thechamfering-knives.

Similar letters refer to similar parts throughout the several views.

In the drawings, A is the cast iron knifeblock ordinarily used inveneencutting machines.

a is the body of a curved cutting-knife, which is secured to theknife-block A by the adjustable bolts 0 c c c.

b is a curved steel knife-blade which is riveted onto the knife-body aand is used espeoially for cutting curved veneers. In Fig. 1

the corners of this knife are broken away, showing the chalnferingknives in place. i

d d are two chamfering knives which are inserted in the slots 6 6 (shownin Fig. 3) in the knifeblock A. and are adjusted by means Serial No.647,544. (No model.)

of set-screws, one of which is shown at f in Fig. 2.

Mare the blades or cutting parts of the chamfering-knives,which areformed to chamfer any bevel desired.

g is the presser-bar, which is curved at the face edge to correspondwith the curved knifeblade I) and is set at a distance from the curvedknife-blade 1) corresponding to the thickness of the veneer required.

13 is a clamp which holds the presser-bar g and the chamfering-knives dd rigidly in place. This clamp is pivoted at P, and its pressure uponthe presser-bar g is controlled by the set-screw Q, which passes throughthe outer end of the knife-block A.

O is a portion of a veneer-bolt, showing its relative position to theknives and presserbar while being operated upon.

In Fig. 4. the curved presser bar g, the curved cutting-knife. blade I),and the chamfering-knives cl d are shown in their relative positionto'each other as they would appear in a plan view, the space asrepresenting a section of a veneer as it would appear after being out bya curved knife and chamfered on both edges by the chamfering-knives 01d.

When the machine is in operation, the veneer-bolt O is revolved againstthe cutting edge of the knife-blade b, which is automatically fed towardthe bolt 0, as required, the severed veneer passing through between theknife-blade b and the presser-bar 9, when it thencomes in contact withthe blades 11 i of the chamfering-knives cl cl, where it is chamfered tothe desired bevel.

What I do claim, and desire to secure by Letters Patent, is-

In a veneer-cutting machine, the knifeblock, and a curved knife-bladesecured thereto, combined with the knife-block provided with grooves e,the pivoted clamp, the screw Q, the presser-bar 9 held in position bythe clamp, the two charnfering-knives placed in grooves in the block Aand held .in position by the presser-bar, and the screws f for adjustingthem, substantially as shown and described.
